Method for separating and recovering target polymers and their additives from a material containing polymers

摘要

The invention relates to a method for separating target polymers and their additives from a material containing polymers, as a result of which the recovery both of the target polymers and of the additives is made possible. Based on the principle of a selective precipitation, the target polymer is precipitated and subsequently separated from the additives present in solution and dissolved foreign polymers. The separation of the additives from the solution is effected in a further step.
